A source with the Players Association told the Herald that the union is prepared to take their concerns about the Marlins’ salary cutbacks to Bud Selig if the club doesn’t increase payroll in the coming months.

“We don’t have to wait until October to pursue it,” the source said.

Former commissioner Fay Vincent says the Marlins better not take this situation lightly, either. Vincent told the Herald he expects Selig and the union to “strongly encourage” Marlins owner Jeffrey Loria to up his payroll.

“They can make it very uncomfortable if he doesn’t,” Vincent said.

Still, don’t be surprised if the Marlins ignore the union’s concerns. For one reason, the club claims it lost $40 million in the first year at their new ballpark, according to the Herald. Also, while opening-day payroll is expected to come in around $32 million, the Marlins have to spend another $12 million-plus on players they traded, which in essence gives the club a payroll of about $45 million.

If the Marlins are ordered to spend, it won’t be the first time. Before the 2010 season, the commissioner and the union forged an agreement that required the Marlins to raise payroll for three straight years. They did, too, and began 2012 with a payroll of more than $100 million.

But after finishing in last place, the Marlins have returned to pinching pennies on players’ salaries.
